Reflection of Waves
Reflection occurs in waves when they encounter an obstacle and are made to propagate in the opposite direction as shown in the diagram below
Reflection also occurs in sound and light waves. Sound heard after reflection of sound waves is called an echo.
Refraction of Waves
Refraction occurs when the wave is made to travel through two media of different densities. Refraction is the change in the speed and direction of the waves as they cross the boundary between two media of different densities. The incident angle (i) is the angle the direction of the incident wave front makes with the normal (N) at the boundary surface. The angle of refraction (r) is the angle the direction of the refracted ray makes with the normal (N) to the plane boundary.
